Currently have 2 routers with HSRP. A trace route passes from active router but after changing the standby router to a newer model with same config as before a trace route passes from standby router instead of active.
How come? From sh standby the main router is active but I am seeing the standby router (old and new) are both in Init states.

Hi,
first of all I didn't understand the final architecture: do you have two or three routers on the segment ? In any case could you post the config and the result of the show standby for each router ?
Bye

Hi
This example activates a port, sets an IP address and a priority of 120 (higher than the default value), and waits for 300 seconds (5 minutes) before attempting to become the active router:

HSRP V1 and V2 are compatible with each other. Group numbers have increased in V2 to 4095 from 255 in V1.
I would double check your configs again after checking out this LINK about conversion to V2. Although V1 and V2 are compatible it's sometimes wiser to start eliminating any possible issues. If the older router is compatible with a newer IOS, update it to match the new router. IOS feature versions for V2 are also in that link.

Enrico,
Thanks for the correction.
"HSRP version 2 does not interoperate with HSRP version 1. An interface cannot operate both version 1 and version 2 because both versions are mutually exclusive."
Sounds like he needs to make sure both routers are running the same HSRP version and his problems "may" go away.
Thanks,
Matt

The initial post talks about the standby is in init state.
If this is true it would indicate that the interfaces is not in up state. If they where up but with different hsrp version, both routers would be active.
